FDA and CDC Announce on November 9 That the Multistate Outbreak Linked to Alfalfa Sprouts Has Ended: The Recalled Alfalfa Seed Lot SAL2-24JB Was Tied to 77 Illnesses in 16 States, With 6 Hospitalizations and No Deaths, and the Investigation Is Complete
WASHINGTON — In a November 9 update to its outbreak investigation page, the U.S. Food and Drug Administration said that a multistate outbreak investigated by the FDA and the Centers for Disease Control and Prevention (CDC), with state and local partners, is over: the CDC has declared the outbreak over and the FDA's investigation is complete. The outbreak was linked to recalled alfalfa seed lot SAL2-24JB and involved multiple serotypes of Shiga toxin-producing E. coli (O26:H11, O103:H25 and O168:H8) and a strain of Salmonella Agona.
As of November 9, a total of 77 people were reported infected across 16 states: 64 people were infected with E. coli, 10 with Salmonella, and 3 with both. Illnesses started on dates ranging from May 31, 2026 to October 19, 2026. Of the 52 people interviewed by state and local officials, 41 (79 percent) reported eating sprouts in the week before becoming ill, and 36 specified alfalfa sprouts. There were six hospitalizations and no deaths. The 16 states with cases are Florida, Indiana, Iowa, Kansas, Michigan, Minnesota, New Hampshire, New York, North Carolina, North Dakota, Oregon, Pennsylvania, South Carolina, South Dakota, Washington and Wisconsin.
On the product side, Berlin Seeds-branded alfalfa sprouting seed was sold at the company's retail store in Millersburg, Ohio, and through its website from February 13 to August 23, 2026; Berlin Seeds recalled 950 pounds of the seed on September 23. Lot SAL2-24JB was also shipped to sprout growers and wholesale distributors in 16 states and Puerto Rico and distributed internationally to Canada, Mexico, Tahiti and Venezuela; the lot carries an expiration date of December 31, 2029. The FDA said sprouts grown from the recalled lot are past their best-by dates and should no longer be available for sale, and that growers should check their inventory for the recalled lot and discard any remaining seed, while consumers should check their homes for the recalled products and throw them away. This report states the official findings and disposal information only and offers no individual medical advice.
